Frage von momentum:
I produce with the GY-HD101E in HDV1 mode (720/p25) and capture via FireWire camcorder s.demselben in Edius Neo, usually as Canopus HQ AVI.
Unfortunately, I have nogrosse idea of technical details to record sounds. For studio recording I record the sound with a microphone (Rode M3) from a distance of about 1.5 meters. The microphone is fed into both channels. CH1 and CH2 is auto leveled manual. The controller for CH2 is at maximum (10).
Question 1
---------
No matter what I do: The sound on auto leveled CHF1 is (too) quiet. The manual leveled sound on CH2 reasonably enough. In most cases, must be because the average synonymous turn up a bit. But then a noise is heard.
Menu AUDIO / MIC, there is the setting AUDIO REF.LEVEL. selected default is-20dB. Alternatively at-12dB. I note now that the sound is noticeably louder with-12dB. That annoys me but that JVC writes in the manual: "Use-12dB when playing the recorded tape with a normal DV Device." I do not know. Nevertheless, I observe better results.
What now? From now work with-12dB?
Question 2
---------
Also in the menu Aduio / MIC, there is the setting INPUT MIC REF. Default is-50dB according to Manual. Alternatively, it is possible-60dB.
What should I choose or how to find this out?
Antwort von Horace83:
I know the M3, but that you are in manual audio control and crank up the volume quite as reasonably ok designated nest is a bit strange.
What you take as to exactly? Language, atmosphere?
Do you have ne damping s.Microphone switched?
If your tone is too quiet, the way the Reference Level to -12 to make already not bad. Have containing less headroom, but it seems not even to clipping.
If none of this helps anything, you just have to say I ran closer would.
Can you run with a tape and the sound is as synonymous to quiet?
Antwort von momentum:
Thanks for the quick reply!
I refer to Language: actor before blue screen.
Damping is Noan. With the Micro Camcorder is the same.
So the sound would even with clipped audio control "10," I would have to speak powerfully loud cry to. Indeed, this is not a problem.
Closer ran hard.
tape I can run with before. Will I make good time but, even only for Comparison (Zoom H4n).

Hello Momentum
Your Microphone yes converts sound pressure into voltage. At a defined sound pressure is (without defect) created a certain tension s.einem certain degree.
You can use the measure itself is very bad because you have to work with a reference sound pressure, They are at 1kHz at a distance of 1 m 10 high-12 W/m2.
From the area and type of your microphone is now arise whether s.Abschluss -50 or -60 db. (Or even synonymous another value). Microphones age way synonymous with dust or moisture on the approximately 2-3y strong film and give Sun synonymous worse values. So, -50 is not wrong.
By the way, the microphones with the tiny membrane surfaces always at a disadvantage compared to larger microphones with membranes.
For audio control -12 or -20 db
The reference level in the EU in the broadcast area-20dBFs. This corresponds to the analog domain 6dbv s.600 Ohm (0 VU) or +4 dbv in SMPTE area.
Normally would be your attitude.
Now this is the level that is really only of relevance for the final product.
If you so choose this setting for the camera, you will reach full output only when really gives the oA sound pressure, which is generally not the case, as is usually the source to much of the camera away, or just too quiet.
In this respect, the setting is entirely on your shooting situation s.aber if you get along better with -12, there is nothing.
You just need careful that it does not suddenly "the bomb burst" because that you can not forgive a digital system.
Incidentally, as with the "get closer" You can reach with a directional microphone.

Well knowing that I'm not doing anything wrong with the setting. The Level I course, keep in mind.
The camera microphone is more focused than the aforementioned Rode M3. I should perhaps put more on it.
When can I choose the way Rode (PAD switch): -20 dB, -10 dB and 0 dB. Currently 0 dB is selected. The vote would not you?
Gruss, Roman
Antwort von WoWu:
Zero is ok. Any loss would be counter-productive.
As for the noise, it is mainly the (presumably) of the microphone for the camera, because if I recall correctly, had a very good signal to noise ratio.
Since only acoustic pressure really helps! The Rod3 has, as far as I know synonymous its strengths in the high level range because it makes it sound pressures up to 135 db or so of the order. So maybe really is not that the happiest choice for voice recordings.
(But that's just a thought, because I have not worked with the Micro)
Antwort von momentum:

As for the noise, it is mainly the (presumably) of the microphone for the camera, because if I recall correctly, had a very good signal to noise ratio. I think you're wrong: I started because of the noise with JVC contact. I was told that the XLR-boards are not exactly brilliant. In the next model they had been fundamentally renewed for it (or something like that). I left it at a reasonable cost (the camcorder to my heart) my XLR-board exchange on which the noise had already improved markedly.
The VAD-testers praised in the 3 / 2010, the Rode M3 as an all-Micro for voices, sounds or instruments. It was just about synonymous essential for the use of video and offer a natural sound. Maybe you yourself like an image? You can find the technical specifications
Antwort von WoWu:
Hi Roman
Strangely, we have no difference in signal to noise ratio of the 100 and 200 models had ... at least not in my memory but may be that we have received in the 100ern for service intervals, the new boards.
In terms of values and the concepts, we must always see the application. A voice or vocal microphone is everything. For one, the microphone close and sing loudly and speak into synonymous loud. Part of this is the present, with a relatively small capsule, well made, because the transmitted sound pressure db 130 is relatively high.
Bad ones, as I have already suggested, the noise values with 21 db are clearly high. Good microphones are 3-5db and with reversible characteristics customarily db at 8-10. Now it does nothing, of course, if the signal to noise ratio of the camcorder is already over, but I do not think (I got the values right now is not handy).
Anyway, I would for a voice recording, which takes place in more than one meter always a micro with low noise levels used, the preamp I generated enough level to work s.Camcorders in the linear part of the gain can and not the regulation raise up to the stop need. Typically, the preamplifier better in the microphones, as in the camcorder electronics. But as it looks good sometimes synonymous, right?
Maybe even the return as a rhetorical question: is the part connected correctly or it sounds a bit "sharp"? Then there could possibly still be a cause.
Antwort von momentum:
Granted, Wolfgang, the technical background that you write, I can with my knowledge does not quite follow. The key messages to come yet - clear and understandable. Thank you for this!
[...] Close and sing loudly and speak into synonymous loud. Part of this is the present, with a relatively small capsule, well done, [...] So you are likely right, because when I used to Kommentaraufsprache near the mouth, it delivers good I think (better) results.
Can you from the technical specifications of the camcorder still pick out something interesting (see below)? Perhaps they contain the information that you did not have on hand.
Maybe even the return as a rhetorical question: is the part connected correctly or it sounds a bit "sharp"? Then there could possibly still be a cause. Hm Now you überfrägst me. I'm not quite as audiophile that I'm in "acute" could imagine something. Also, I'm not quite sure what you mean with "properly connected". The mic is connected through the XLR connectors with phantom power supply s.CH1, or "MIC +48 V". But you probably do not think (because one can not go wrong synonymous). XLR cable I have "from a pro" is used, so do not solder yourself.
A Tonkostprobe you can
Antwort von WoWu:
Hello Roman,
thanks for the link to the post. You are with the Micro too far away.
Therefore, the low level probably synonymous. You are already with the microphone outside the room radius. That is the point s.dem the reflected sound the same or greater than the direct sound entrance is the Microphone. point at which the result is quite unpredictable because it is synonymous cancellations that you really no longer have under control.
You must either ran thick, (you could catch up or of the micro-dependent) or use higher directivity (eg, super-cardioid or best) or you use a badge. Einwenig sharp sounds, the mixture, but probably comes from the processing. Does not sound to an incorrectly connected micro.
I think that the problem with the signal to noise ratio is then completed. Am taking a test, with the micro of up to fish.
I once watched, the Micro is 79 EUR. Nothing against low-cost devices, but the camera you were allowed to quietly buy something better. I know budgets are small, but a micro device is an important work, because man is more sensitive to bad sound, than a bad image.
But to me, will send a snippet sound over. But I think it will not sound much different.
Until then
Antwort von momentum:
Hello Wolfgang
Your explanations make sense, they match the actual shooting conditions. So I thought I would have chosen a poor area (Hall) ...
Fishing is unfortunately difficult, since there are often one-man productions. Micro button would be an alternative. Also try hanging I could (would certainly fit the polar pattern of the microphone). Otherwise, I should in this situation, probably more likely to work with the Kameramik (about 11 cm long tube), which shows a result of your statements more clearly.
I have attached a ZIP folder s.diesen review. It contains the first 30 seconds of sound, convert to WAV (otherwise untreated). Also, I've attached a JPG. You can tell it the position of the microphone.
Now I lay me down to sleep and greet you.

Antwort von WoWu:
Jau, Roman, same problem in the sound. Micro seems to be ok, but if you pull the level, there is a sound course of it .... So get with the Micro and perhaps even synonymous einwenig insulate the room. I would start with a carpet. This makes little work, helps a lot and rarely interferes. :-)
SNR way, I have only-18db below peak level (-24 -6 db to say on the track) .... this is nothing ... much too little and comes with no security of the camera. Times urgent attempt another microphone.
Edit:
I'll be tomorrow times over playing a small speaker sample that is made with the camera, just to compare the signal to noise ratio. I come tomorrow s.die tapes.
Antwort von hofnarr:
... I do not even know if it is the original Micro. with the search term MV-P615U you can find on google to compare several illustrations. The microphone is a short and very light shotgun of plastic without any labeling, and the cable is fixed s.mikrofonkörper connected.
for your application actually provides the use of a tripod as overhead boom. inexpensive and sufficiently robust (but not very easy to transport) have for instance this:

s.dem you can test as the existing mount rode m3, but I would try the synonymous micro camera there, the sound quality may be sufficient with careful alignment then already.
